Imagemagick - Getting the usable dimension of an image - imagemagick

Question

I've a process which is creating a file with convert (ImageMagick) based on some parameter, and after that it checks the file and gives back the biggest dimension of it which has real pixels.
The commands look like this:
convert -size 5000x5000 xc:white -font {font} -pointsize {size} -fill black -draw "{some_occassional_additional_parameter}text 200,2500 \"{text}\"" {some_other_occassional_additional_parameter}{temporary_file}
convert {temporary_file}.png -trim +repage -format "%[w]x%[h]\n" info:
. It'll result something like: 526x425
This process runs half a million time per day, and it seems to be a huge bottleneck. I'm looking for a solution which can done this in memory, so not always creating a file and check it, but do it in memory somehow.
If can speed it up just like 50%, that'd be a huge achievement.
Thank You

Not at a computer to test, but change your first command to:
convert -size ... xc:... occasionalstuff -format "%#" info:
Note that you can, and probably should double quote the "%#" especially if you use expressions containing characters of significance to the shell, though it is not strictly necessary in this specific case.
